Forces
Newton laws of motion
1st: “An object will remain at rest or
continue with constant velocity unless acted on by an unbalanced force.”
2nd: “The acceleration (for a body/object of constant mass) is proportional to, and in the same direction as, theunbalanced force applied to it.”
3rd: “When one body or object applies a force to another, the second body or object will apply a force equal in size but opposite in direction to the frst body or object.”

Kinematics
As velocities and accelerations are devided by time, the values obtained will depend on the duration over which the measurement is made.
The velocity or acceleration when the time is very nearly zero is called the instantaneous velocity or acceleration, and may be calculated in two ways.
